Abstract: An automated film encoding and decoding system for bringing photographic film from the state of exposure to subject matter through all of the processes required to produce finished photos and package the same. The system includes an encoder coordinately operative with a camera for the placement of a human and machine readable code on the film the decoder capable of reading the code for the control of production-processing equipment in laboratories provided with such equipment. The human readability of the code accommodates production-processing of the film by attendant personnel and also allows for quality control check of automated production-processisng equipment. The encoding includes film frame identification information, subject matter information and registration mark information all of which may be utilized on a single exposure situation.
